Information
Plexiglass is a popular building decoration material recently, but some people think that there is no difference between plexiglass and general glass from the literal understanding, which is not correct. In order to better let more people understand the professional knowledge of this kind of products and facilitate the distinction between products, let's first understand the differences between the two:
1. High transparency: plexiglass is the most high-quality transparent polymer material at this stage. The light transmittance exceeds 93%, which is higher than that of glass. Ordinary glass can pass only 0.7% UV light, but plexiglass can pass 74%.
2. Light weight: the density of plexiglass is 1.16kg/dm3. The net weight of materials of the same size is only half of that of ordinary glass and 44% of that of metal aluminum (belonging to light metals).
3. High mechanical strength: the relative molecular weight of plexiglass is about 2 million. It is a long-chain polymer material chemical, and the molecular chain is very soft. Therefore, the compressive strength of plexiglass is relatively high, and the tensile strength and impact resistance are 7 ~ 16 times higher than that of ordinary glass. Therefore, the plexiglass processed by Rashin can be used as bulletproof glass and as the cockpit cover on military aircraft.
4. Convenient for production and processing: plexiglass can not only be cut by CNC lathe and drilled by drilling machine, but also be bonded into various shapes of equipment such as acetone and chloroform. It can also be processed into various products such as aircraft cockpit cover and denture sleeve and tooth support by plastic molding such as injection molding, injection and extrusion.
5. Performance distinction: generally, if the thickness of glass exceeds 15cm, it will become emerald green, and the objects cannot be seen clearly through the glass. Plexiglass separated by a meter thick, but also can clearly see the opposite items. Because its light transmission performance is very good, and ultraviolet light can penetrate, it is often used to make optical equipment.
